Dear Fedi, I have another question.

I've noticed some time ago that most of my Linux devices have two IP addresses in my local network, on a single wlan interface (192.168.1.127 and 192.168.1.128 in this screenshot)

Both of them work - I can ping those addresses from another device in a local network.

Why is that so? Why two addresses for one network interface? And how?

@kuba maybe some docker containers running?

@kuba
sorry I dont really know. Its just a guess. I would expect that Docker uses internal addresses and uses NAT to reach out to external services like the wild wild web. But hey, i've seen some weird shit out there.
I've come to that conclusion because I've seen VM's in VMware which had also multiple IP addresses on there external interfaces and they had some docker containers running.
But it doesnt mean that this is what you are experiencing. But maybe you could test it

Ich habe jeden Film und jede StarTrek Serie mindestens 1 mal durch, die Meisten davon mehrmals. Aber mit der original TOS Serie und dem Zeichentrickableger davon tue ich mich schwer. Um die Historie, die Geschichte vollständig zu haben und es politisch wie auch geschichtlich einordnen zu können, versuche ich es immer mal wieder. Irgendwann schaffe ich es auch noch, aber es fällt mir schwer.
Damals wäre ich wohl kein Fan geworden.
